How many members of the group are male?

We are given that there are two housewives, one lecturer, one architect, one lawyer and one accountant among A, B, C, D, E and F.

The other information given is that only two married couples are in the group.

We are given that the lawyer is married to D, and D is a housewife.

We are also given that no woman in the group is either an architect or an accountant.

C is an accountant, has to be male, and is married to F, who is a lecturer, who has to be female.

Putting this information in the table, we get,

We are also given that A is married to D, so this has to be the second couple, and A has to be the lawyer.

This leaves us with B and E, as well as housewife and architect professions. Given that E is not a housewife, E has to be the Architect and B has to be the housewife. Since the Architect cannot be a woman, E has to be a man, and B has to be a woman.

Putting all the information in the table, we get,

From the table, we can see 3 males in the group.

Hence, the correct answer is option B.
